Resumo | This work is an extension of previous analysis (1) which has studied the influence of hydrogen in the methane diffusion flames. In this paper the aim is to determine the stable condition for methane diffusion flames enriched by hydrogen in different levels of flame stretch The stretch on the flame is provided by the flow field imposed by two opposed streams, one of them is constituted by mixtures of hydrogen, methane and nitrogen and the other is constituted by air. The flow field conditions correspond to fuel stream velocities in the range 0.1 to 4.0 m/s, which are chosen to compare the results of the present analysis to those from the n-heptane diffusion flame. The result presentation follows the flamelet model, the flame properties are presented as a function of the scalar dissipation χ = 2(λ/ρcp)(dZ/dx) 2 , whose unit is s −1 ; Z is the mixture fraction. The reciprocal of scalar dissipation χ −1 at the flame is a measure of the residence time of the reacting substances inside the flame. The results pointed out that methane diffusion flame without and with hydrogen is not strongly influenced by stretch. For mixtures with high hydrogen concentration, this influence is even smaller. For a fixed fuel mixture concentration (YCH4 + YH2), the flame temperature increases with the increase of the hydrogen mass fraction as a consequence, mainly, of the increase of the overall heat realised and, secondarily, of the reduction of the radiative energy losses via CO2 radiation. |
